Hi Monty,

That EVolution 3 phase charger will only charge the Kona at 7.2Kw max or around 50km/h as it only has a single phase 32A charger on board.

The NRMA is calling for potential partners such as local councils and community groups to express their interest in working with the NRMA to bring a charger to their local area. Visit mynrma.com.au/future-is-electric

Tyre Repair

How are Kona EV owners reconciling tyre repair? As the car only comes with a compressor and tyre goo, there is no option for tyre replacement should the tyre sealant not work. The Kona roadside assistance package is contracted to the NRMA. The terms and conditions of that policy, state that if a tyre is unrepairable the vehicle is to be towed at the owners expense.

If you are caught out in a non metro area that could become quite costly.

2020 EU Kona Ev to get onboard three-phase onboard charger with up to 11 kW (AC), Blue Link app and optional navigation system with a 10.25-inch centre display.

I wonder if the 11kW 3-phase is actually three independent 15A chargers, one for each phase, so this might be a disadvantage when only single phase is available? Perhaps you would then get just 3.6kW charging? Alternatively, perhaps the car is smart enough to run two of those chargers in parallel if an EVSE says single phase 32A is available for 7.2kW? Does anyone know?

I'd be surprised if it didn't support single phase charging, particularly given the US market is nearly all single phase charging

I am not suggesting that it would not support single phase charging. I expect the three phase charger would operate on one phase if it only found power applied to one input. My question is whether that would be limited to 15A rather than 32A.

Kona EV 2019 battery capacity.
Stated as 64 kWh.
So why do my first 2 calculations suggest 78kWh?
Where is my error?
Estimated Capacity = Charged amount kWh divided by percentage SOC increase x100
Just two days recorded properly at this stage.

Perhaps you could ask your Hyundai dealer or Hyundai's national technical help line? No, sorry, only kidding! Obviously they wouldn't have a clue.

My guess is that the battery management system (BMS) might still be learning where the battery limits are. My previous iMiEV instructions suggested occasionally discharging to 2 bars or less followed by a full uninterrupted charge to help the BMS to recalibrate for a more accurate battery gauge, counting amp-hours in and out of the battery.

This seems to be a common arrangement.

I think it depends on the EVSE. Some wire L1, L2, and L3 in parallel, and some leave L2 and L3 disconnected. (I thought that they should randomly supply any of L1, L2, or L3, so phase L1 doesn't get overloaded). If they wire in parallel, then you'd get 11 kW. If they don't, you'd get 3.6 kW.
Alternatively, perhaps the car is smart enough to run two of those chargers in parallel if an EVSE says single phase 32A is available for 7.2kW?
I don't think that car can do much in the way of smarts. There is also the hassle of interpreting what a current limit of say 15 A means for a 3-phase EVSE. Does it mean 15 A per phase, or 15 A total? [ Edit: especially if you're a single phase EVSE, and you've paralleled the pins. Some vehicles will have one charger on one pin, and some will have three chargers on 3 pins. ] Usually, 15 A 3-phase means 15 A per phase. But it seems that some vehicles can overload some EVSEs with this confusion.
Does anyone know?
Alas, I don't know. The above it all speculation and impressions gained from reading various articles and posts.

Is that kwh measured AC in?
If so, keep in mind the charger isn't 100% efficient, and the rest of the cars systems don't draw nothing (running 12v, cooling battery, etc)

so AC kwh in is somewhat higher than dc kwh that actually gets stored

Good point Matt! Hard to guesstimate the difference too. Will continue to record and monitor.

After dropping the battery to 5% from 100% charge by a day trip Perth-Bunbury-Perth i recharged at UWA to 45% SoC in 35mins. The result is a battery capacity maxed predicted at 66kWh not the previous 78KWh so the BMS may have settled. I should have taken it 100% again but will do another time. Thanks fo rate tips.
